Rear-Facing
When installed in the rear-facing position, the child
seat should be reclined at least 30˚ from vertical for
children and up to 45˚ from vertical for infants unable
to maintain head and neck control (not to exceed
45˚) when the car is parked on a level surface. When
installing the seat in rear-facing mode, recline the
seat to position 3 and use the guide line on the child
seat to help achieve an acceptable recline angle for
rear-facing installations.
Forward-Facing
IMPORTANT: In forward-facing installations, it is important that the base of
the child seat rests completely flat on the vehicle seat. As illustrated below,
it is permissible to allow up to 20% or 3 in. (7.6 cm) of the base to hang
over the edge of the vehicle seat. Some vehicle seats do not allow enough
of the child seat base to contact the vehicle seat. If this is the case, adjust
the recline angle to a more upright position. Not doing so could cause the
child seat not to perform as intended.
